问题描述

What is the difference between the Schema.org properties isPartOf and hasPart and when to use the one instead of the other?

推荐答案

如其页面上所述，它们是逆属性.

As noted on their pages, they are inverse properties.

以一个示例为例，假设一个网站是网站的一部分.然后，您可以声明以下其中一项:

As an example, let’s take a webpage that is part of a website. You could then state one of these:

• WebSite hasPart WebPage

WebPage isPartOf WebSite

选择哪一个都没关系. (但是当然，可能有些消费者只认识其中一种属性.)

It doesn’t matter which one you choose. (But there might of course be consumers that only recognize one of these properties.)

注意:大多数情况下，Schema.org并未为属性定义反向等效项.例如，有 author ，但没有 authorOf .这是因为在语法的帮助下，您可以将两个方向的每个属性都使用:

Note: Most of the time, Schema.org doesn’t define an inverse equivalent for a property. For example, there is author, but no authorOf. This is because you can use every property for both directions, with the help of the syntax:

• RDFa:
  rev
  (示例)

• RDFa:
  rev
  (example)

微数据:
itemprop-reverse > (非标准，这是使RDFa优于微数据的原因之一)
(示例)

Microdata:
itemprop-reverse (non-standard, which is one of the reasons to prefer RDFa over Microdata)
(example)

JSON-LD:
@reverse
(示例)

JSON-LD:
@reverse
(example)
